Hope everyone's year is off to a great start!
The beginning of the year has been exciting for Trnio. We recently updated the app with a new soft setting - perfect for faces, people, animals, and food. This blog post demonstrates how to create a face scan.
Setting up the scan
First, before starting the scan, ensure there is good lighting. Dark lit rooms will reduce the quality of the scan. Likewise, aiming the phone directly into the sun will wash out a scan. In this example, we found an outdoor covered area. Secondly, have the person sit down if possible. This will help the person from moving. They will need to keep still for the approximate 20 seconds it takes to move around a person.
User interface Explanation
To start the scan, press the Trnio camera button and select object mode (rectangle). Press the person icon (bottom left) to turn on soft mode. Also, pay attention to the light sensor on the bottom right. Anything over 3 bars is great lighting. If you have low lighting, move slowly around the person to reduce blur.
The video below shows the scan process. The linked 3D model is the output from this video. Notice as I move around the person, the phone is vertical. This is important to get under the chin and nose. I went around once, but you can zig-zag back to get above the head as well.
The example above is of a 180 degree capture. To capture a 360 model, continue the scan until you go back to the starting ear. Afterwards, press and hold the circle at the center of the screen to save the scan.
Face Scan output
This is the 180 degree scan from the video above. We are now working on improving scans for people with long-hair.
